The invention discloses an elevator door operating device. A fixing groove is additionally formed in a main lower door operator arm, a spring pin is additionally arranged on a door operator base plate, and a driving check block and an unlocking check block are additionally arranged on a driving arm. The spring pin is always embedded into the fixing groove of the main lower door operator arm in the whole movement process from closing of a landing door to almost full closing of the landing door, a main door operator cannot generate displacement, when the landing door is almost completely closed, the spring pin is separated from the fixing groove, and the main door operator can be far away from a slave auxiliary door operator; and before the door is closed to be close to the full-closed state, although the driving check block can be separated from the main lower door operator arm, the main lower door operator arm cannot rotate in an anti-clockwise manner due to the pulling force of a spring assembly because a pin head of the spring pin is still inserted into the fixing groove of the main lower door operator arm. The elevator door operating device not only can guarantee the advantages of an original asynchronous door operator, but also can avoid the situation that the landing door cannot be closed due to the fact that the landing door is affected by the external force and makes contact with the main door operator, the device is of a pure mechanical structure, the structure is simple, the cost is low, and the device is safe and reliable.
本发明公开了一种电梯门刀装置,在主下门刀臂增加固定槽,在门刀底板上增加弹簧销,在驱动臂上增加驱动挡块及解锁挡块,使从层门开始关闭至层门几乎全闭的整个运动过程中,弹簧销始终嵌入主下门刀臂的固定槽中,主门刀无法产生位移,待层门几乎完全关闭时,弹簧销才与固定槽脱离,主门刀可以远离从门刀;而在关门至接近全闭之前,虽然驱动挡块会脱离主下门刀臂,但是因为弹簧销的销头仍然插入在主下门刀臂的固定槽内,主下门刀臂不会因为弹簧组件的拉力而逆时针旋转。该电梯门刀装置,既能保证原有异步门刀的优点,又能避免出现层门被外力影响导致与主门刀接触引起层门无法闭合的情况,并且为纯机械结构,结构简单,成本低,安全可靠。
